Gretchen DillonGretchen Dillon
glasser@syr.edu

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Pennsylvania State University - University Park (Animal Sciences/conc)

Personal Statement
I'm a 2nd-year masters candidate in concurrent degree programs of Forest Ecology and Ecosystems (M.S.) and Public Administration, with a concentration in Public and Nonprofit Management (M.P.A) and a certificate of advanced study (C.A.S) in Conflict Resolution. What I enjoy about my degree program: the attitude and accessibility of faculty and staff, my major professor's ability to challenge me, the opportunity to attend classes on other campuses (SU!), and my research site, which is in the white mountains of New Hampshire.

Graduate Research Topic
Nutritional Effects on Causal Organism of Beech Bark Disease in Aftermath Forests

Favorite Quote
Pour y voir plus clair, il suffit souvent de changer de point de vue.

Favorite Hobbies
Moth and insect ID, Birding, backpacking, cycling, travel, xc skiing.

My Graduate School Mantras
(1) Read everything that you're given. (2) Just because I don't understand right now doesn't mean that I'm incapable of understanding. (3) When in doubt, whip it out. (translation: stop doubting and get it done!)

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Environmental Monitoring
  • Undergraduate Institute: Trinity College (Hartford CT) (Environ Science)

Graduate Research Topic
I am currently working on two projects. The first one is a chronosequence study on American beech interference with sugar maple regeneration in the White Mountain National Forest where I am also looking at the responses of the two hardwood species to nutrient manipulations, soil chemistry, and stand age. The second one is on foliar chemistry of yellow and white birches and their resorption proficiency and efficiency in nutrient-manipulated plots in the White Mountain National Forest.

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Allegheny College (Environmental Science)

Graduate Research Topic
I am currently studying the effects of nutrient additions (N, P, N+P) on the sap flow in sugar maple trees.


Adam WildAdam Wild
adwild@syr.edu

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai
  • Area of Study: FRM Ecology and Ecosystems
  • Undergraduate Institute: SUNY Cobleskill

Personal Statement
My interest span across multiple aspects of forest ecosystems and factors that influence plant productivity.

Graduate Research Topic
I am currently studying the health and productivity of sugar maples based on available soil nutrients in the White Mountains of New Hampshire. My research project is striving to determine what nutrients influence the sugar concentration of maple sap and whether maple sap sweetness can be increased by application of calcium, nitrogen, or phosphorus fertilizer in a forest stand.

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai
  • Area of Study: FRM Ecology and Ecosystems
  • Undergraduate Institute: Minzu University of China (Environmental Science)
  • Previous Graduate Study: SUNY-ESF (Forest and natural r)

Personal Statement
I'm interested in forest-based environmental issues that raised currently. I'm more focused on nutrient cycling and mercury pollution in forests.

Graduate Research Topic
My current project is quantifying total mercury in different tree components at four sites (Huntington Forest, NY; Sleepers River, VT; Hubbard Brook, NH; Bear Brook, ME). I am also analyzing mercury by tree rings and doing data analysis of loon Hg.


Alex YoungAlex Young
aryoung@syr.edu

  • Degree Sought: MS
  • Graduate Advisor(s): Yanai
  • Area of Study: Ecology and Ecosystems
  • Undergraduate Institute: Lewis & Clark College

Personal Statement
I am fascinated by tree canopy dynamics, specifically microclimate gradients that are associated with height in a tree such as humidity and light availability.

Graduate Research Topic
I am currently examining the effects of nutrient additions (N, P, N*P) on the vertical gradient of foliar traits in sugar maple canopies.
